ADM00557, Evaluation Board Using MCP8024 TQFP BLDC Motor Driver

ADM00557, MCP8024 TQFP BLDC Motor Driver Evaluation Board demonstrates the MCP8024 3-Phase Brushless DC (BLDC) Motor Gate Driver in a BLDC motor drive application. The MCP8024 contains the high-side and low-side drivers for external N-channel MOSFETs. A dsPIC33FJ32MC204 motor control processor is used to supply the PWM inputs to the MCP8024 as well as handle the high-speed Analog-to-Digital Conversion (ADC) required for 40 KHz PWM operation. The MCP8024 on-board UART is used to configure the MCP8024 and to send fault information to the dsPIC controller. The evaluation board firmware uses a 6-step trapezoidal drive control algorithm to demonstrate the MCP8024 capabilities
